Provided is a wireless power transmitting device (1) of a wireless power supply system, that includes a wireless power transmitting unit (10) that includes a variable resonant circuit (100) having a variable-controllable resonant frequency characteristic and that wirelessly transmits electric power via the variable resonant circuit (100). Resonant frequencies (f1 to f3) of the variable resonant circuit (100) are variable-controlled by a power transmission control unit (13). Wireless power receiving units (20) that include unique resonant circuits (200A to 200C) that are different to each other are provided in wireless power receiving devices (2A to 2C), respectively. The wireless power receiving units (20) wirelessly receive electric power from the wireless power transmitting unit (10) as a result of the unique resonant circuits (200A to 200C) tuning to the resonant frequencies (f1 to f3) of the variable resonant circuit (100) to generate a magnetic field resonance mode. |
